Troubleshooting
Device does not power on after inserting battery
Ensure the battery is correctly inserted with the positive (+) and negative (-) terminals in the right orientation. Clean the battery contacts in the device with a pencil eraser or a dry cloth. Try a new battery, as the inserted one may be depleted or faulty.
Device operates intermittently or weakly
Check for any signs of corrosion on the battery contacts. Ensure the battery is fully seated in its compartment. If the issue persists, the battery may be low on power or the device may have a higher power requirement than this battery can supply.
Battery drains faster than expected
This battery is designed for low-drain devices. If used in a device with higher power demands, it will deplete more quickly. Verify the device's compatibility with this battery type and capacity.
